Pigmentai ir užpildai. Dispergavimo procedūra sedimentacija pagrįstam skendinčių pigmentų ar užpildų dalelių dydžio nustatymui taikant sedimentacijos skystyje metodus (ISO/DIS 20427:2025)

This document specifies sample preparation methods to determine the size distribution of separate particles of a single pigment or extender, which is dispersed in a liquid by application of a standardized dispersion procedure, using an ultrasonic device, shaker device or wet jet mill. The sample preparation methods described are optimized for measurements carried out with a particle sizing technique based on sedimentation. This technique relies on particle migration due to gravitation or centrifugal forces and requires a density contrast between the particles and the liquid phase.

Nešiojamieji gesintuvai. 7 dalis. Charakteristikos, veikimo reikalavimai ir bandymo metodai

This document specifies the characteristics, performance requirements and test methods for portable fire extinguishers. Reference to the suitability of an extinguisher for use on gaseous fires (Class C fires) are at the manufacturer’s discretion but are applied only to powder type extinguishers which have gained a Class B or Class A and Class B rating. Suitability of extinguishers for use on Class D fires (fires involving flammable metals) is outside the scope of this document in respect of test fires. However, extinguishers claiming Class D suitability are covered in all other respects by the requirements in this document for powder extinguishers. It is considered hazardous for powder and carbon dioxide fire extinguishers to be used on Class F fires. For this reason, powder and carbon dioxide fire extinguishers are excluded for conformance with regard to Class F in this document. NOTE The extinction of a metal fire presents a situation so specific (in terms of the metal itself, its form, the configuration of the fire etc.) that it is not possible to define a representative standard fire for the purposes of testing. The efficiency of extinguishers on Class D fires is established on a case by case basis.

Vandens kokybė. Nurodymai, kaip imti bentosinių stambiųjų bestuburių ėminius iš upėse ir upeliuose esančių buveinių proporcingai pagal jų dydį

This document gives guidance on procedures for the pro-rata multi-habitat sampling of benthic macroinvertebrates in rivers and streams. The term “pro-rata” reflects the intention to sample all the main riverine habitats present at a monitoring site according to the proportion of the site that it covers. It is an objective way to divide sampling effort among the different habitats. This guidance is applicable to all flowing waters, both artificial, modified and natural. This design enables comparable samples to be collected from any type of river, regardless of the habitats present. The pro-rata multi-habitat sampling is an overall approach rather than a specific method. This document is designed to: — support environmental and conservation agencies to meet the monitoring requirements of the WFD (Article 8, Annex II, and Annex V); — generate data sets appropriate for monitoring and reporting of sites designated under the Habitats Directive and the Birds Directive ensure that samples for comparing the overall composition of invertebrates from different stream types are comparable; — ensure samples for environmental quality assessments across different stream types are comparable even when sampled by different people; and — support river management and restoration initiatives. The pro-rata multi-habitat sample (MHS) provides: — a consistent way of sampling sites that is not dependent on the presence of particular types of habitat; and — guidance on a user-friendly strategy for collecting biological data depending on the distribution of substrate type. It is also ideal for: — understanding the distribution of biological community types across different physical river types; and — quality assessments based on deviation from reference, as adopted in the European Water Framework Directive.
